which version of corel draw do you prefer to use and why?

I use corel draw X3, there is many features like, opening an image directly, and dealing with it as normal object.
Also smart filling tools, easy grouping.
And creating objects...

corel draw12 version because i think it is very easy for work. 

I use Corel draw version 12 mostly because i have features like Double click Crop tool (the first vector software able to crop groups of vectors and bitmap images at the same time), Smart fill tool, Chamfer/Fillet/Scallop/Emboss tool, Image Adjustment Lab.
Trace became integrated inside Draw under the name PowerTrace.
